Application
Amidase from Pseudomonas aeruginosa has been used for testing its capability to hydrolyze ochratoxin A.[1]
The importance of these hydrolases in biotechnology is growing rapidly, because their potential applications span through chemical and pharmaceutical industries as well as in bioremediation. Immobilized amidase can be used efficiently for production of acrylic acid from acrylamide, thus converting a toxic ambient contaminant into widely used industrial raw material. Amidases are potential treatments for human immunodeficiency virus and malaria. They may be used to eliminate metal ions in wastewater [2].
Biochem/physiol Actions
The amidase from Pseudomonas aeruginosa isa 6 × 38-kDa enzyme that catalyzes the hydrolysis of a small range of short aliphatic amides. Each amidase monomer is formed by a globular four-layer αββα sandwich domain with an additional 81-residue long C-terminal segment [2].
Unit Definition
One unit will convert 1.0 μmole of acetamide and hydroxylamine to acetohydroxamate and ammonia per min at pH 7.2 at 37 °C.
Physical form
Solution in 50% glycerol containing 7 mM 2-mercaptoethanol and phosphate buffer salt

Filamentous cyanobacteria of the order Nostocales display typical properties of multicellular organisms. In response to nitrogen starvation, some vegetative cells differentiate into heterocysts, where fixation of N(2) takes place. Heterocysts provide a micro-oxic compartment to protect nitrogenase from the oxygen
